What can change the nature of man?
Mass extinction that almost eliminates the species, but leaves a remnant that is not at all typical of the whole species. For example a war that wipes out 7 billion, leaving only 50 million, and they are all Norwegians or Swedes. Man, would now be a much smaller sample, and quite diffferent one. Man would change his spots, as it were, by changing the sample, and the sample size, and the character of the sample. Apart from such a cataclysmic event man’s nature is pretty constant, if history is any guide. If you ask questions where the truthful answer is bound to be harsh and non-PC, then please don’t be surprized if you get back a straight but not so pleasing to think about answer from me. Mentats just tell the truth — that’s what they do — it like Fair Witnessing except it applies to the present and future as well as the past.
